Though there are often conversations about the health of larger minority groups such as African-Americans and Hispanic-Americans, smaller groups are a real worry for an increasingly overburdened government health care system.

When we search the cosmos for evidence we are not the first advanced life form, we look for things that we could share in common. This anthropomorphism is common in culture, in everything from science studies to science-fiction. And it may not be wrong.

Assuming we have any extra-terrestrial neighbors, far less popular is the idea that we will be the advanced civilization new ones are terrified about being invaded by, they will likely have undergone natural selection just like we did. In the video game Spore, almost everyone evolved creatures that were purple and had huge eyes, despite trying to do things randomly, and that may happen on other planets also.

Though it is commonly believed that wealth leads to better health and less discrimination, wealthier African- and Latino-Americans report more racial discrimination than poor ones, according to survey results. Meanwhile, as whites became more wealthy they report improved health.

Though genetically engineering food using science remains controversial in some circles, with concerns about genetically modified corn syrup in candy and claims that CRISPR can somehow be harmful whereas mutagenesis-derived foods can be labeled organic, progress marches on.

We're on our way to 9 million people and existing agriculture could easily handle it...if great agricultural land were evenly distributed. But is isn't evenly distributed, which is why the US and Europe can have robust markets for food created using an organic-certification process. Yield does not matter, just profit margins do, when land grows food easily.

Traumatic brain injuries in baseball and softball are down, but they were not really all that high to begin with, and that may be why there is poor compliance overall with helmet use and return-to-play guidelines following concerns about a concussion.

This will be a surprise to American and British public health officials, who know cigarette smoking has plummeted and even among those who get hooked, vaping is considered a viable harm reduction and smoking cessation alternative.
